Question

which is bigger 4/5 or 8/9 ?

please answer me clearly ​

Answer 1

Answer:

To compare any two fractions, we must always find the equivalent fractions of the two which have the same denominators.

So, we have to find the equivalent fractions of 4/5 and 8/9 which have the same denominators.

If you don't know what equivalent fractions are, you won't be able to understand this. But if you do, this is a piece of cake. Considering the latter possibility, I will solve this question.

4/5 can also be written as 36/45

And, 8/9 can be written as 40/45.

Now, we have to compare:-

$\frac{36}{45}<\frac{40}{45}$

So, the answer is 8/9.

Answer 2

Given :  Fractions 4/5 or 8/9

To Find : Which fraction is

Solution:

Fractions 4/5 or 8/9

Fractions can be easily compared if denominators are equal

create equivalent fractions :

By dividing or multiplying the numerator and denominator of a given fraction by the same number except zero

a/ b  = ak/bk      k ≠ 0

a/b  = (a/k) / (b/k)   k ≠ 0

4/5  

Multiply and divide by 9

= 4 * 9/(5 * 9)

= 36/45

8/9

Multiply and divide by 9

= 8 * 5/(9 * 5)

= 40/45

40 >  36

=> 40/45  > 36/45

=> 8/9 > 4/5

Hence 8/9  is bigger
